I see this on Pinterest and Instagram all the time tagged as a "botanical tattoo," so maybe start there. It's hard to narrow down suggestions without knowing where you are, especially since so many people are dabbling in this right now because of demand. Somebody might have an idea if you give a ballpark area of where you live.
I've recently become a fan of Pis Saro's work. https://www.instagram.com/pissaro_tattoo/?hl=en
I can't tell you how much I love her subject matter and her style. Sadly, I don't live in Europe. Can anyone think of an American tattoo artist who creates similar work?
